Hi Heather,

That sounds really smart. The current wisdom is that breast milk has no vitamin d, but that's only because mother's don't get enough vitamin d to have any to spare.

But the literature shows very nicely that if a mother is Vitamin D sufficient that her breast milk has PLENTY of vitamin d. And that's good for the both of you! You can read about that on my Vitamin D and Breastfeeding page.

Your doctor will likely tell you that you are taking too much, but on the vitamin d and breastfeeding page above, you'll see that you need 5600 IU's a day for 6 months just to get enough vitamin d in your breastmilk to meet your baby's needs.

Just make sure that you are taking Vitamin D3 and not Vitamin D2.

As far as Vitamin K is concerned while pregnant, I have to say that I am simply not familiar enough with the research on Vitamin K and pregnancy to help you out there.

vitamin D whilst pregnant
by: Anonymous

I have been taking vit D3 2500iu by pure pharma as recommended by my coach for several months, i have been a regular crossfitter for 3yrs now & have continued excerising throughout my pregnancy. I am now 11+ 6 wks pregnant & started panicking tonight when i realised i have been taking over the recommended dose. I am a natural ginger with paleskin & avoid sunlight and requires total sunblock if out in sun. Have i put my baby at risk????

Too Much?

You're WAY more likely to be taking too LITTLE, not too much. Especially if you have only been taking Vitamin D for several months and you have avoided sunlight all of this time.

2500 is the amount recommended for a toddler, not an adult, and especially not a pregnant adult. A recent study shows that maternal vitamin D supplementation reduces the risk of premature birth. And there were no risks to the baby, on the contrary, almost certainly the risks of autism, mental illness, bone loss and other problems to the baby were reduced, not increased.

The study was done using both 2000 IU's a day and 4000 IU's a day. The women taking the higher doses decreased their risk of preterm birth by 50% IF THEY REACHED A BLOOD LEVEL OF 40 ng/ml.

That is a level I seriously doubt that you are even close to having almost certainly been vitamin D deficient for many years.

More studies on Vitamin D and Breastfeeding indicate that getting 2000 IU's a day of vitamin d gets you a zero IU increase in breastmilk over taking 400 IU's a day.

At 4000 IU's a day, women had increased their vitamin D levels, but not enough to meet a baby's minimum daily needs. Only at doses of 6400 IU's per day, and only after they had taken that dose for 6 months, were they able to produce enough vitamin d to meet their baby's needs.

There was also one study done following a women who had to take 100,000 IU's of vitamin d per day for a specific medical condition. She went through pregnancy, birth, and breastfeeding and had a healthy baby without vitamin d toxicity or other problems.

So, think about it, would nature only put vitamin D in breastmilk at levels to meet baby's needs at a dose of 6400 IU"s per day if 2500 IU's was going to damage your baby?

It's far MORE likely that you need 6400 IU's a day in order for your baby to be healthy. What we DO know for sure is that 4000 IU's a day is DEFINITELY safe, and is actually more beneficial than taking 2000 Iu's a day.

So, ideally, you get a Vitamin D Test, something that your doctor is negligent for not having done, and take 'enough' vitamin d to get your level to 40 ng/ml.
